Blue caves definately worth doing, but the ship wreck - not so much unfortunately.

 

Glad I've been but wouldn't go again, too many people on the beach at one time, "beach" hurts your feet, the water is colddna dangerous as small boats plowing in to drop more people off and because of the amount of boats there the diesel fumes are terrible

But like I say, the blue caves are definately worth the trip, and will be going again next time I go
